Patented Sept. 6, 1932 UNITED STATES LOUIS B. HYDE, OF DETROIT, MICHIGANELECTRIC HOT WATER HEATER Application filed March 17, 1930. Serial 1T0.436,395.

My invention relates to a new and useful improvement in an electric hotwater heater and has for its object the provision of a hot water heatercomprising a tank and having projected inwardly of the tank a heatingelement encased in a water proof housing and adapted for easy and quickremoval therefrom and replacement therein.

Another object of the invention is the provision in an electric 'hotwater heater of a supporting member for the hot water tank which willserve to generally support the tank in upright position and permit theeasy and quick removal and replacement of the electric heating elementfrom its enclosing housing. 4

Another object of the invention is the provision of a supporting basefor a hot water tank and provided with securing mechanism which willprevent rattling and relative 2 movement of the various parts.

Another object of the invention is the provision of a supporting basefor hot water tanks so constructed and arranged that the base, whilemade of light material, will possess a maximum stren h and be providedwith reinforcement at t ose parts which are subjected to strain.

Other objects will appear hereinafter. The invention consists in thecombination and arrangement of parts hereinafter described and claimed.

The invention will be best understood by a reference to the accompanyindrawing which forms a part of this speci cation and in which, i

Fig. 1 is a central vertical sectional view of the invention showing itapplied with a part of the tank broken away.

Fig. 2 is a view taken on line 2-2 of Fig. 1 reduced in size.

Fig. 3 is a fragmentary view of a modified form of attaching the heatingelement housing in positon. p

In the drawing I have illustrated the invention used with a hot watertank 7 having a top 8 and a base 9. The tank is enclosed in an outershell or casing 10 having the base 11 and the top 12, the base 11serving as a support for the hot water tank. The tank 7 is provided withthe inlet pipe 14 which leads I into the thermostat water jacket 15which communicates with the interior of the tank 7 and to which leadsthe conduit 16 from the box 17 to conduct the cables to the thermostathousing 18. Thebottom 9 is provided withan opening 19 in which isengaged the open end 20 of the housing 21 which is used to enclose theheating element 22 which is wound on the core 23. Extended through thecore 23 is a pipe 24 which engages in the neck 25 of the inner end ofthe housing 21. A lateral opening 25 is formed in the upper end of thepipe 24 thus permitting the water to enter the pipe 24 from the side soas to render less interference with the upward flow of the heated water.A plug 27 serves to close the lower end of the pipe 24. The pipe 24conducts the water ccntrall of the heating element so as to increase t eheating efficiency thereof and may be drained of scale and other solidmaterial which may accumulate therein upon removal of the plug 27. Anopening 29 is formed in the base 11 through which the plug 27 isaccessible so that this draining may be effected without disman- 7tlingthe structure. The lock nut 26 is threaded on the pipe 24 andserves to retain the core I 23 in position, the flange 30 engaging theinner surface of the housing 21. This housing 21 is provided with aperipheral flange 31 and is secured, in Fig. 1, by the bolts 32 to thebase 9, a gasket 33 being positioned therebetween. In the form shown inFig. 3 this housing is threaded into the base 9', the

base 9 being provided with an inwardly projecting boss 34. A pipe 36 ispositioned in embracing relation on the housing 21 so as to engage theoutwardly projecting radiating ribs 37. The base 11 is mounted on legs38 which serve to support the entire structure and at each of the legs38 there is mounted in the base, the supporting blocks 39 and 40'. Ametal plate 41 is mounted on the upper surface of each of theblocks 39and serves to engage the lower edge of the tank 7 for supporting thesame. These blocks are positioned at each of the legs 38 and serve toreinforce the base at the points which support the tank 7. r p p While Ihave illustrated and described the preferred form of construction I donot wish to limit myself to the precise details of struc ture shown butdesire to avail myself of such variations and modifications as may comewithin the scope of the appended claims.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is:

1. In a hot water heater of the class described: a water containerhaving a bottom provided with an openin a housing secured in saidopening and projecting inwardly of said container; a tube projectingthrough the inner end of said housing in communication with the inte iorof said container and terminating at one end outwardly of saidcontainer; a removable plug for closing the outer end of said tube; aninsulating core mounted on said tube; a heating element wound on saidcore; and means for retaining said core in position in said housing.

2. In a hot water heater of the class described: a water container; abottom on said container; an insulating casing enclosing said container;a convex bottom on said casing in spaced relation to the bottom of saidcontainer; supporting legs secured to and projecting outwardly from saidcasing bottom adjacent the periphery thereof; supporting blocks mountedon the inner surface of said casing bottom at the location of said legsthe upper surface of said blocks being extended horizontally and thelower face of the outermost of said blocks being shaped to conform withthe curvature of the inner surface of said casing bottom.

3. In a hot water heater of the class described: a water containerhaving a bottom provided with an opening; a housing secured in saidopening and forming a closure therefor and projecting inwardly of saidcontainer, the outer end of said housing being of larger diameter henthe inner portion of said housing; a tube projecting through the innerend of said housing and communicating with the interior of saidcontainer one end of said tube extending outwardly of said housing andsaid container; an insulating core engaging in said housing andembracing said tnbe; a flange on the outer end of said core engaging theenlarged portion of said tube and serving as an outer closure for theinner portion of said tube; and means LOUIS B.
